In the United States, nationally representative data on student achievement come primarily from two sources: the National Assessment of Educational Progress (NAEP), also known as “The Nation's Report Card”; and U.S. participation in international education assessments, including PIRLS, TIMSS, ICILS, and PISA. While the international assessments may appear to have significant similarities with NAEP, each was designed to serve a specific purpose and each is based on a separate and unique framework and set of assessment items. Thus, each gives a somewhat different view of U.S. student performance.
To help readers understand the similarities and differences between the assessments and to help identify what the international education assessments and NAEP each contribute to the overall knowledge base on U.S. student performance in reading, mathematics, and science, NCES provides detailed information on the purposes, target populations, reporting levels, and content assessed through PIRLS, TIMSS, ICILS, and PISA in comparison to NAEP.
The following comparison reports are available, with the most recent ones listed first:
